Mixed feelings about the price of such items. I have been engaging in

when people want it.
Some manufactureres seem to be cooperating by making pdf versions of old
product manuals available online.
In some cases, yes. However some other makers seem to be becoming more
'cautious' about issuing information like this. For example Quad used to
quite happily send out their service manuals, etc, to anyone who wanted
them. Yet I had to put a lot of effort into even getting the circuit
diagram for the 988's. :-/
Is there anything in particular you are looking for?
Short answer: *Everything I don't already have*. 8-]
Longer answer:
I tend to specialise a bit in info on 'Armstrong' as I used to work for
them. However I now have a lot on the ranges from about the 400/500's in
the 1960's and a fair bit on some of their valve amps, tuners, etc. There
are some holes, though, so I don't have copies of all the user manuals and
diagrams for the A10's, A20's and previous models. I have data on many of
their previous chassis models but this is often limited to publicity stuff
giving a photo, a valve list, and a brief circuit description, not a
diagram.
More generally, I have a fair bit on makers like Quad, but less on many
other makers, including many who are now largely forgotten. (e.g. from the
early 'class A' transistor period being FAL)
In general terms, I have been collecting product info, publicity material,
circuit diagrams, reviews, service manuals, photos, recollections from
those involved, etc. The broad area is 'audio/hifi UK manufacture and
design during the last 100 years or so'.
I spend time occasionally scanning documents and photos so that copies can
be made available. The basis of what I am doing is 'academic/historic' not
commercial. So I don't sell the results. Instead I use it as a resource for
giving advice/info to those who may have old kit and want to use / service
/ restore it. If someone can let me have useful new additions to the
collection I am then happy to send them a CDROM or two of what I already
have as a 'thank you' in return.
Started doing this some years ago as a result of doing a google for
"Armstrong Audio". Got loads of references to moon landings and trumpet
playing, but none to audio. :-)
Decided that I'd better get back in contact with people who used to be
involved in UK audio manufacture and collect info before we all dropped off
our perches and the info was lost. ;-
Thus the "Armstrong" website and the (now quite large) collection of
documents that hide behind it...
Did an analysis on the stats that demon provide a while ago and was pleased
to see that the website gets a fair number of file requests per day. No
idea how many of them are into moon landings, though. ;-
If you have any docs, etc, that you think may be of interest, and you may
be willing to loan / scan /donate please email me with the details. In
exchange I'd be happy to let you have copies of useful items I have
already. Apart from smaller files/collections I do this via posting paper
or CDROMs as I only have an old-fashioned phone modem link.
Slainte,
Jim
